In the time of smart cities, there is a variety of applications where the localization of indoor environments is necessary, from monitoring and tracking in smart buildings to adjacency marketing and advertising in shopping complexes. The prosperity of these applications is based upon the progress of a cost efficient and robust real-time system capable of precisely locating objects. In most outdoor localization systems, global positioning system (GPS) is used because of its ease of implementation and efficiency up to five meters. But, due to the limited space related with performing localization of indoor environments and the large number of interference found indoors, GPS is not a suitable option. Therefore, flawless and efficient locating of objects is a major challenge for indoor environments. Recent growth in the Internet of Things (IoT) along with recent wireless technologies can ease the problem. Small-size and cost-efficient IoT devices that use wireless protocols can provide an interesting solution. In this paper, we compare four wireless technologies for indoor localization: Wi-Fi (IEEE 802.11n-2009 at the 2.4 GHz band), Bluetooth low energy, Zigbee, and long-range wide-area network. The received signal strength indicator (RSSI) values from Wi-Fi modality were used and trilateration was performed for localization. The system anticipates the location of the user inside a room, and performs action based on the location of the user in the bounds.
